Re: System Sometimes Hangs @ "Power Off" While Halting

My Lenovo X60 always hangs at "power off". This has been true for months, I can't recall exactly which update I first noticed it, but no update since has fixed it. Removing the laptop-mode daemon also does not fix it.

pm-suspend works as expected, but shutdown seems to do everything except turn off the power.

does your network adapter uses the e1000e module? if so, have you tried removing that module before shutdown to see if that temporarily solves the problem?

Is this issue still present in the latest kernel from core?Non of the above workarounds had worked for me but after reading this post and this article, I added the following to the kernel command line and the problem no longer appears.

pcie_aspm=force

I'm on a Thinkpad x301 running kernel26 2.6.39.3-1 from core.

Yes, the problem is still present with the latest kernel from core. I reproduced it now by removing the e1000e module from the blacklist. Adding "pcie_aspm=force" didn't work for me. The only solution I found is blacklisting e1000e.

Re: System Sometimes Hangs @ "Power Off" While Halting

Dear all,

I had already posted my worry in a <a href="https://bbs.archlinux.org/viewtopic.php?id=122416">Laptop Issues thread </a>. It passed unanswered, so I guess it's more relevant here. If I am breaking the netiquette by restating my problem, please disregard this message and accept my apologies:

I would like to ask you for help with a weird piece of behaviour of my arch box (now 3.0, but it was the same with older kernels), a Toshiba Satellite U500:

* Shutdown works OK when on A/C, but, when on battery, the computer ends up with fans on and the On button light on. In this state it is totally unresponsive -- it looks much as it does when it fails to suspend.

* But, on battery (and A/C too), it reboots perfectly well. So I've resorted to rebooting when I want to shutdown on battery, and then plugging it off once it gets to the bios screen.

I'm sure these will be tell-tale symptoms to more enlightened arch users. For my part, I am totally clueless. I would have suspected an acpid problem, but I have no shutdown event or action enabled. I don't see anything interesting in the logs either. Although my computer is now arch only, I've had several Ubuntus, Mints and Fedoras installed, and Windows 7 too. This issue has only appeared on arch.

What Ethernet chipset does your laptop have? Does it use the e1000e module? If so try this as root:

Re: System Sometimes Hangs @ "Power Off" While Halting

I have the same problem, I think, but none of the solutions offered have made a difference. I run an Acer Aspire One, with a network chip using the ath5k module. Unloading this module before shutting down doesn't help, however. The e1000e module doesn't run in the first place.

You should report this issue to bugzilla.kernel.org when kernel.org is back. Obviously the "rmmod e1000e" is just a workaround to this problem, there seems to be a more deeper issue. I hope we can find a way to trace the root of the problem and fix it.

Re: System Sometimes Hangs @ "Power Off" While Halting

Also, there seems to be two new bug reports about the issue with shutdown and e1000e. According to Zhang Rui from Intel, the issue is caused by the e1000e runtime suspend. The issue also seems to be related to WOL (Wake-on-LAN).
